Abstract

Zirconium-containing BaO- and PbO-free X-ray opaque glasses having a refractive index nd of about 1.480 to about 1.517 and a high X-ray opacity with an aluminum equivalent thickness of at least about 180% are provided. Such glasses are based on a SiO2—B2O3—Cs2O—K2O—La2O3 system with additions of Al2O3, Li2O, Na2O and/or ZrO2. Such glasses may be used, in particular, as dental glasses or as optical glasses.
